Tobar Lumez Tornado Lamp - Colour-Changing

What you're getting

Watch coloured water swirl endlessly inside this tornado lamp. The vortex keeps moving, creating that hypnotic effect kids find properly absorbing — and honestly, it's oddly soothing to watch when you've had a day.

Runs on batteries, so you can stick it anywhere without hunting for a plug. The colour-changing feature means it shifts through different hues as it spins, which keeps things fresh enough that it doesn't get boring after a week.
